| The eluents were analysed with a differential refractometer and the peak areas were integrated by a Spectra Physics 4290 integrator. |
|
| Calibration may be done by known solution value or by comparison to a refractometer. |
|
| The Abbemat WR-MW digital refractometer enables quick and fully automatic measurements of the dispersion and Abbe number. |
|
| Before and after workouts, he tested urine samples with a refractometer to monitor how he coped with dehydration in the buildup to Beijing. |
|
| The Brixxus CRI 245 F is an automatic critical angle refractometer used to determine concentrations in a carrier medium. |
|
| Ballast water salinity is checked using a hand held salinity refractometer or with an electronic meter. |
|
| Instruments to monitor chemical properties include the refractometer, infrared analyzers, chromatographs, and pH sensors. |
|
| In its simplest form, grape sampling might consist of selecting some berries haphazardly from the vineyard and expressing juice into a refractometer to measure sugar content. |
|
| Discerning the difference between a gas and liquid thus requires a refractometer that can measure slight differences between critical angles and reflection intensities. |
|
| Since the viscosity of the concentration depends on the temperature, it is recommended to use a refractometer for calibration and recheck. |
|
| Use of the Goldberg refractometer as a salinometer for biological and geological field work. |
|
| Our programme to minimize problems associated with corrections of air buoyancy is well advanced with the ability now to monitor changes in air density using a novel refractometer. |
|
| Experienced gemologists could identify nearly every kind of gem with just a refractometer, a polariscope, a set of specific gravity liquids, a spectroscope and a binocular microscope. |
|
| In 1896 the British physicist Lord Rayleigh described the Rayleigh interference refractometer, still widely used for determining the refractive indices of gases and liquids. |
|
| The refractometer measures the amount of sugar in a few drops of juice. |
|
| The Rhino VET 360 refractometer quickly and accurately determines urine specific gravity and protein concentration in plasma, serum and peritoneal fluid. |
|
| In our case the refractometer was used just for relative measurements. |
|
| If you use significant amounts of PG ES Coolant for top off, freeze point measurement must be done using a refractometer if accuracy is important. |
|
| The PMD700 Compact is the optimal process refractometer for users who have low requirements in terms of resolution, measuring range, and connectivity, but don't want to compromise on quality. |
|
| The two artefacts and the heart of the refractometer, a double Fabry-Perot interferometer, were placed inside the FB-2 balance case, which is equipped with accurate devices for measuring the ambient air parameters. |
|
|
|
| Typical applications for the smallest cooling thermostat in the world are external closed systems e.g. photometer, refractometer and viscosimeter. |
|
| Very easy to use, the Pen Pro refractometer generates readings in around two seconds and, because readings are continuous, any inhomogeneity can be readily identified. |
|
| The TSSC readings were made by refractometry using an Abbe refractometer. |
